GROUP
F
NOTE
• The range of frequency changeable by acceleration signal (RH) and deceleration signal (RM) is 0 to maximum frequency
(Pr.1 or Pr.18 setting). Note that the maximum value of set frequency is (main speed + maximum frequency).
• Even if the start signal (STF or STR) is OFF, turning ON the RH or RM signal varies the preset frequency.
• The RH, RM, or RL signal can be assigned to an input terminal by setting Pr.178 to Pr.189 (input terminal function
selection).
Changing the terminal assignment may affect other functions. Set parameters after confirming the function of each terminal.
• The inverter can be used in the Network operation mode.
• The remote setting function is invalid during JOG operation and PID control operation.
• The multi-speed operation function is invalid when remote setting function is selected.
• Even when the remotely-set
frequency is cleared by turning
ON the RL (clear) signal after
turning OFF (ON) both the RH
and RM signals, the inverter
operates at the remotely-set
frequency stored in the last
operation if power is reapplied
before one minute has elapsed
since turning OFF (ON) both the
RH and RM signals.
• When the remotely-set frequency
is cleared by turning ON the RL
(clear) signal after
turning OFF (ON) both the RH
and RM
signals, the inverter operates at
the
frequency in the remotely-set
frequency cleared state if power
is reapplied before one minute
has elapsed since turning OFF
(ON) both the RH and RM
signals.
